BISMARCK — North Dakota Gov. Doug Burgum and Minnesota Gov. Tim Walz both directed flags to be flown at half-staff in honor of the victim of the Friday, April 2, attack on the United States Capitol in Washington, D.C.

Flags in both states are to be flown at half-staff until sunset, Tuesday, April 6.

William "Billy" Evans, an 18-year veteran officer of the U.S. Capitol Police, was among the deceased after a motorist rammed a vehicle into officers and brandished a knife. The attack caused the Capitol complex to go on lockdown, though police did not initially suspect the attack was terrorism-related.

A second Capitol Police officer was injured as well.

Burgum's and Walz's orders follow a proclamation from President Joe Biden which also ordered flags to be flown at half-staff.
